New 'GoFetch' Vulnerability in Apple Silicon Exposes Encryption Keys

Researchers uncover a hardware-level flaw in Apple's M-series chips that cannot be patched, posing a potential risk to cryptographic data security.

A newly discovered vulnerability in Apple Silicon, named 'GoFetch,' allows attackers to bypass encryption and access cryptographic keys.
The flaw affects M1, M2, and M3 chips and is unpatchable due to its hardware-based nature, leaving current devices vulnerable.
Researchers suggest software-based mitigations to reduce risk, but these could significantly impact performance.
Intel's Raptor Lake CPUs also feature the DMP responsible for the vulnerability, but their implementation prevents the attack.
The vulnerability recalls previous significant CPU flaws like Spectre and Meltdown, highlighting ongoing security challenges in chip design.
